NEAR CHEMNITZ, GERMANY RING FOR SPINNING AND DOUBLING FRAMES Application filed December 24, 1931, Serial No. 583,105, and in Germany March 4:, 1931.

Traveller rings for spinning and doubling frames have been proposed, which consist of part rings which are connect/ed together and the dividing gap between which serves for the passage of the lubricant. Through this gap the race of the traveller is lubricated. It has been found that frequently too much lubricant, f or instance oil, is conveyed to the race. This is more particularly due to the fact that through the rapid rotary motion of the traveller within the ring a partial vacuum is produced, through which the oil is drawn by suction. V

According to the invention an excessive oil supply is preventedby the dividing gap between the part rings being filled with an intermediate body, preferably an absorbent material, for instance felt, woven fabric or the like. This material is intended to function as a retarding material. Through the employment of this material it is possible by narrowing or widening the dividing gap to adjust the oil supply very accurately. The invention thus makes it possible to regulate the oil supply very finely. The supply of lubricant can be accurately adapted to the partial vacuum prevailing in the ring, which may vary very considerably in accordance with the speed of revolution of the traveller.

The invention is illustrated by way of example in the accompanying drawing, in which y Fig. 1 is a partial section through a doubling ring according to the invention,

Fig. 2 a partial section through a spinning ring according to the invention,

Figs. 3 and 4 also sections through spinning rings of somewhat different constructional 0 forms and to a slightly smallerscale.

The doubling ring illustrated in Fig. 1 consists of the part rings a and b, which are releasably connected together, for instance by a thread 0. Between the part rings at the level of the traveller path is an annular gap d, through which from a lubricant reservoir 0 a lubricant can pass into the interior of the ring. a, b are those points on the part rings a and 6 against which, or in the vicinity of which, the traveller bears during its passage around the ring in the interior thereof.

According to the invention in the annular gap (13 .and preferably in the space e as well an absorbent'material f, for instance felt, wick, woven fabric or the like, is placed. This material allows only just so much lubricant to pass through as is necessary for lubrieating the traveller path.

Easy regulation is possible by the absorbent material f being compressed to a greater or less extent in the annular gap d by the part rings a, I) when correspondingly more or less oil will pass through.

The space 6 communicates through an opening 9 with an oil pipe, oil squirt or the like.

A packing it between the part rings prevents oil escaping through the thread 0.

The ring shown in Fig. 2 is a spinning ring. It consists of two part rings 1 and 2 with the dividing gap 4. The part ring 2 is pressed by a further part ring 3, into the part ring 1. The passage 1 is that point on the lower side of the ring flange or ring head against which or in the vicinity of which the traveller comes in contact during its passage around the ring. 5 is a lubricant reservoir. According to the invention the dividing gap 4 and the lubricant reservoir 5 are filled with an absorbent material 6, for instance felt or woven fabric. 7 is an opening forconnecting to an oil pipe and 8 is a packing between the different part rings.

In'the construction shown in Fig. 3 the part rings 9 and 10 are held together by a ring of U-shaped cross-section. This ring 8 is slipped from below over the part rings 9 and 10. 12 is again the dividing gap and 13 the reservoir in which the mater1al14 is housed, which has a retarding effect on the flow of oil.

The constructional form shown in Fig. 4 corresponds as regards its details to the constructional form according to Fig. 3, with the exception that in place of the Ushaped ring 11 'a soldered seam 14 is provided, which, 95 holds the two part rings 9 and 10 together.

What I claim is:

1. A traveller ring for spinning and don bling frames comprising in combination with a plurality of part rings, the. said 100 part rings forming a space for the reception of a lubricant and abutting against one another so as to form a vertical slot between two part rings, horizontal flanges on the upper of the part rings, the

5 said flanges abutting against one another so as to form a substantially horizontal slot, the

vertical and horizontal slot for conveying the lubricant to the place of contact of the horizontal flanges by the traveller, the slots which extend over considerable portions of the periphery of the ring being in communication with the space for the reception of the lubricant and an intermediate body in the slots between the part rings.

2. A traveller ring for spinning and donbling frames comprising in combination a plurality of part rings, the said part rings forming a space for the reception of a lubricant and abutting against one another so as 90 to form a vertical slot between two part rings, horizontalflanges on the upper parts of the part rings, the said flanges abutting against one another so as to form a substantially horizontal slot, the vertical and horizontal slot for conveying the lubricant to the place of contact of the horizontal flanges by the traveller, the slots which extend over considerable portions of the periphery of the ring being in communication with the space for the reception of the lubricant and an oil-pe-rvious intermediate body in the slots between the part rings.

3. A traveller ring for spinning and donbling frames comprising in combination a lurality of part rings, the said parts rings orming a space for the reception of a lubricant and abutting against one another so as to form a vertical slot between two part rings, horizontal flanges on the upper parts of the part rings, the said flanges abutting against one another so as to form a substantially horizontal slot, the vertical and horizontal slot for conveying the lubricant to the place of contact of the horizontal flanges by the traveller, the slots which extend over considerable portions of the periphery of the ring being in communication with the space for the reception of the lubricant, an oil-pervious intermediate body in the slots between the part rings and a third ring for holding both part rings together.

4. A traveller ring for spinning and donbling frames comprising in combination a plurality'of part rings, the said part rings forming a space for the reception of a lubricant and abutting against one another so as to form a vertical slot between two part rings, horizontal flanges on the upper parts of the part rings, the said flanges abutting against one another so as to form a substantially horizontal slot, thevertical and horizontal slot for conveying the lubricant to the place of contact of the horizontal flanges by the traveller, the slots which extend over considerable portions of the periphery of the ring being in communication with the space for the reception of the lubricant, an oil-pervious inter-mediate body in the slots between the part rings and a third ring for holding both part rings together, the third ring having a U-shaped cross section and being slipped over the two part rings, and a packing between the part rings.
